A few things that helped me:
Note cards- Pros: Very good tool for visual learners, as well as people who learn by writing things down. You can organize them many different ways. You can do matching or fliping. Cons: You are going to have A LOT by the end of the first class, espically when you get to terminology and pharmacology. Some times you will not get through the large amount of information by the time you have the test, hand writing them can be a little slow.
White board- I LOVED MY WHITE BOARDS. This was a great way for me to learn visually. I would write things down repeatedly, without wasting paper. You can work out math problems much easier. You can draw thing like veins/arteries, locations of muscles and organs, the flow of blood through the heart, etc. The larger the white board the better, sometimes small ones can help as well. The only con I can think of is larger white boards cost a lot.
Quizlet- I used this site and app on my phone all of the time. I would type everything out and then while driving have it repeating in my car instead of listening to music. I did not pay for a subscription, but it would not be a bad idea.
Study Groups- I did not do study groups, but I hear for some people they are very helpful. Plus if you are with the right group of people you can focus better, and have a little fun too.
Working- Honestly work in a vet hospital while you are in Vet Tech school. I am a hands on learner, I understood things a little quicker seeing them being done and doing them in a practical manor. You can even work as a kennel tech and ask to watch the techs place catheters and do not be afraid to ask the techs and the doctors a lot of questions.
Family and Friends- DO NOT STOP HAVING FUN! Go out have a drink, if you are legal, with your friends every so often. Or if video games are your outlet, take a break from studying and play for an hour. Sports are your thing, join a league or club so you are forced to take a break at least once per week to have fun. You can have a relationship while in school, personally my boyfriend and I both were working full-time and going to school full-time for the first 2 years of our relationship, it will be 3 years together this fall.
YouTube- There are some great videos out there, everyone will explain things a little different, you just have to find the way you best understand.
Your Professors- Go ask questions, or e-mail them. Do not be scared, they are there to help you even if they do not seem like it sometimes.
Finally, Find what works for you.
